The Château de Chenonceau is a manor house near the small village of Chenonceaux, in the Indre-et-Loire département of the Loire Valley in France. It was built on the site of an old mill on the River Cher, sometime before its first mention in writing in the 11th century. The current manor was designed by the French Renaissance architect Philibert Delorme.Source: Wikipedia The original second manor was torched in 1411 to punish owner Jean Marques. He rebuilt a castle and fortified mill on the site in the 1430s. Subsequently, his indebted heir Pierre Marques sold the castle to Thomas Bohier, Chamberlain for King Charles VIII of France in 1513. Bohier destroyed the existing castle and built an entirely new residence between 1515 and 1521; the work was sometimes overseen by his wife Katherine Briçonnet, who delighted in hosting French nobility, including King Francis I on two occasions. Eventually, the château was seized from Bohier's son by King Francis I of France for unpaid debts to the Crown; after Francis' death in 1547, Henry II offered the château as a gift to his mistress, Diane de Poitiers, who became fervently attached to the château along the river. She would have the arched bridge constructed, joining the château to its opposite bank. She then oversaw the planting of extensive flower and vegetable gardens along with a variety of fruit trees. Set along the banks of the river, but buttressed from flooding by stone terraces, the exquisite gardens were laid out in four triangles.Diane de Poitiers was the unquestioned mistress of the castle, but ownership remained with the crown until 1555, when years of delicate legal maneuvers finally yielded possession to her. However, after King Henry II died in 1559, his strong-willed widow and regent Catherine de' Medici had Diane expelled. Because the estate no longer belonged to the crown, she could not seize it outright, but forced Diane to exchange it for the Château Chaumont. Queen Catherine then made Chenonceau her own favorite residence, adding a new series of gardens. King Henry II's mistress, Diane de Poitiers had the bridge built.Later, Catherine de Medici had it turned into a covered space… The only structure from the original fort that was left standing is the Keep of the Marques Castle, called the Marques tower.
